The tubular sheet is then cut into individual bag segments. The individual bag segments are sewn together along their bottom edge to form the final bag having at least one venting band for the proper venting of the enclosed items.

Abstract: Stable, concentrated solutions of high-molecular weight polyaniline using amines as gel inhibitors. Certain amine compounds (gel inhibitors) are used to form highly concentrated, stable solutions of the emeraldine base form of polyaniline in numerous organic solvents from which coatings, films and fibers are readily prepared without problems associated with rapid gelation which occurs when concentrated solutions are attempted without the use of the gel inhibitors of the present invention. Tertiary amines are used to solubilize low-molecular weight fractions (Mw<120,000, Mn<30,000) of the pernigraniline, emeraldine, and leucoemeraldine oxidation states of polyaniline as concentrated (>20 wt. %) polyaniline solutions, while primary and secondary amines are used to produce solutions having 15-40 wt % of high-molecular weight polyaniline [Mw≧120,000, Mn≧30,000]. Concentrated solutions of polyaniline co-polymers or ring and/or nitrogen-substituted polyanilines may also be prepared.

Abstract: A syringe has two groups of oppositely formed slip-proof straps axially formed on a periphery of the barrel so that when the user is holding the barrel to pull the recycled needle back into the barrel, the user is able to have a firm grip to the barrel. Further, the plunger of the syringe has a square head formed on a distal end of the plunger and extending out of the barrel so as to facilitate the user to pull the needle.

Abstract: A foldable open container formed of a sheet of irregularly shaped hard paper. The container comprises a main board comprising four sectors each having a substantially trapezoidal side board and substantially trapezoidal four bottom boards; and an integral inner board comprising a main portion, four side flaps, and a central hole on main portion. In use, user may insert his/her thumb into a heart-shaped opening on a side flap while holding the container by hand. Hence, for example, a waffle dish containing ice cream may be supported on the central hole. Further, a spoon may hang on an arcuate slot on the main portion.

Abstract: A top cap of a power nailer includes two annular flanges in the interior of the top cap and an annular space is defined between the two flanges. A piston is movably received in the top cap and a tubular body of the piston is movably engaged with the annular space. The two flanges each have a groove which communicates with the annular space. Two seals are engaged with the two grooves so that the piston movably contacts the seals and the flanges are not scraped by the piston.

Abstract: A joint has a first leaf having an inner gear and a second leaf having an external gear meshing with the inner gear. A driving wedge-shaped disk is non-rotatably attached to a shaft and rotatably received between the leaves. A block with an outer wedge-shaped resistant surface is formed on the driving wedge-shaped disk. At least one driven wedge-shaped segment is mounted around the driving wedge-shaped disk. Each segment has an inner wedge-shaped surface to mate with the outer wedge-shaped resistant surface of block. A wedge arrangement is arranged between a supporting base on the disk and each segment to raise the segment as the driving wedge-shaped disk is rotated with the shaft. Accordingly, the angle between the first leaf and the second leaf can be adjusted. In addition, the shaking of the second leaf with respect to the first leaf can be prevented.

Abstract: A touch controlled device with a pressure sensing electronic input pen comprises a main control unit, a pressure signal processing unit, an electronic input pen, a coordinate and button signal processing unit, a touch control panel, and an output interface, etc. The main control unit serves to process the outputting signals from the pressure signal processing unit and the coordinate and button signal processing unit. The electronic input pen has a pressure sensor and a button, the pressure sensor serves to sense the force applied for being outputted with a pressure frequency signal. The touch control panel is connected to the coordinate and button signal processing unit, the tip of the electronic input pen touches the touch control panel so that the touch control panel outputs a coordinate signal and then transfers this signal to the coordinate and button signal processing unit.

Abstract: A branched polyolefin, preferably a polyethylene, and containing branches with even and odd numbers of carbon atoms, may be made by oligomerizing ethylene to an &agr;-olefin using a selected iron containing catalyst, and then copolymerizing that &agr;-olefin with ethylene and one or more other added &agr;-olefins which have odd numbers of carbon atoms. The polymers are useful, for example, as molding resins.

Abstract: The present invention provides a method and tool for restoring a crashed operation system of a computer, for example, by operating under DOS environment to restore a crashed Windows system without requiring a long time setup and reinstallation. According to the present invention, a matching table for short file names to long file names is established for all files (containing directory names) on a disk. Then the long file names can be retrieved from short file names in accordance with the matching table. Since the long file names are stored in Unicode, they are workable for operation systems of any language.

Abstract: Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and &agr;-olefins, and the copolymerization of such olefins with polar group-containing olefins. These and other nickel complexes of neutral and monoanionic bidentate ligands copolymerize ethylene and polar comonomers, especially acrylates, at relatively high ethylene pressures and surprisingly high temperatures, and give good incorporation of the polar comonomers and good polymer productivity. These copolymers are often unique structures, which are described.

Abstract: In the copolymerization of ethylene and acrylate esters, the use of selected acrylate esters suppresses the formation of acrylate ester homopolymer, and/or allows the rapid analysis by 1H-NMR of the amount of homopolymer byproduct present in the copolymer, both aids in manufacturing high quality copolymers. Useful such acrylates include hexyl acrylate, 3,5,5-trimethylhexyl acrylate, 2-phenoxyethyl acrylate and 2-phenylethyl acrylate. The polymers are useful for films and molding resins.

Abstract: Olefins are polymerized by novel transition metal complexes of selected iminocarboxylate and iminoamido ligands, sometimes in the presence of cocatalysts such as alkylaluminum compounds or neutral Lewis acids. Olefins which may be (co)polymerized include ethylene, &agr;-olefins, and olefins containing polar groups such as olefinic esters for example acrylate esters. Also described are certain “Zwitterionic” transition metal complexes as polymerization catalysts for making polar copolymers. The resulting polymers are useful as thermoplastics and elastomers.
